Phytoaccumulation of heavy metals and protein expression by different vegetablesudcollected from various parts of Khyber Pukhtunkhawa Province, Pakistan

摘要

The present study investigates heavy metal uptake and protein expression by different vegetables collected fromudvarious districts of Khyber Pakhtunkhawa province of Pakistan. Statistical analysis of the data showed that maximumudconcentration of Cd, Cr, Ni, Zn were found in radish and spinach, respectively, collected from Peshawar. Maximum Pbudand Mg accumulation were found in cauliflower and pea at Swat followed by coriander at Haripur and minimum Pbuduptake was noticed in radish taken from Nowshehra. Highest Cu uptake was detected in spinach at Nowshehra. Dataudregarding Cd, Cr, Pb, Cu, Ni, Mg and Zn concentration in water samples gathered from different sites of KPK indicatedudthat maximum concentration of Cd was observed in Swat. Maximum Cr and Cu concentration were measured in waterudsamples from Peshawar while maximum concentration of Pb and Ni were detected in water samples from Haripur. Inudcase of soil samples, maximum Cd, Cr, Mg and Zn uptake was observed in soil sample at Nowshehra. Maximum Pb andudNi concentration was found in soil samples collected from Peshawar. Cu concentration was observed to be the highestudin soil at Swat. Protein profile of different vegetables i.e. cauliflower, radish, carrot, turnip, pea, spinach, corianderudand garlic sampled across five different sites showed that uptake of Cd, Cr, Pb, Cu, Ni, Mg and Zn by these vegetablesudcaused the expression of numerous polypeptides.
